[nickstyle]

Hi, I got this laptop with a dead GPU and i have replaced the moderboard same model

The problem the new motherboard does not charge the battery. The faulty motherboard is charging.
In windows the battery is presend and if i plug in the charger is detected
All voltages are present
What i have done :
-i have replaced the BQ chip
-i have replaced the IO chip with the IO chip fron the faulty motherboard
-i have replaced the bios chip with the one from faulty motherboard

Nothng has changed

Any other ideea?

With care, measure and post the voltage to ground of each pin on the BQ charger IC for a review. Do attach the power adapter and battery for this review.

Questions:

1) Same charger IC part # was used for the replacement?

2) BQ and other replaced parts are properly soldered onboard?

3) Is the battery a known good battery? It was the same battery that worked with the fault motherboard?

Found the problem
It was so easy but i have spent few hours to find it
The first mosfet from the power supply circuit was shorted,so it was working like a fuse. I didn`t check as the laptop was working fine.
Now is charging
Thank you for your quick answwr
